Hmmm, I believe I saw a post earlier about the SD card issue, and saying even the class 2 cards should be fine, just as long as it doesn't go past a certain size. Could be wrong. But yea, that is a nice video, IF IT was recorded with the iPhone 4. Either way, the iPhone's video is still much better than the Evo's, I'm disappointed -_-. Look at these 2 screen-shots I just took. I took them when there was the least amount of movement.

Something's not right. Also the numbers at the top left in yellow are the frame rates. Video was set to average, all the best tweaks I can do.
